About Harkness Memorial State Park
Eolia, a 42-room Renaissance Revival mansion, anchors this 304-acre property along Long Island Sound, surrounded by formal gardens and greenhouses. The land is preserved for its historic buildings and grounds rather than left undeveloped. The Connecticut Department of Energy and Environmental Protection oversees the site, which sits on the sound's shoreline in Waterford.
Hours, fees, camping, reservations and closures are set by the park and change often. Check the official park site before you go.
